Repair the mesh errors that stop an STL or 3MF from slicing. Especially useful for raw AI-generated meshes.

SliceReady closes open edges, corrects flipped normals and removes degenerate triangles, then tells you exactly what it changed — and what it could not fix. Take the result straight to Cura, OrcaSlicer, Bambu Studio or PrusaSlicer. It does not thicken thin walls, hollow, remesh or rescale: those change the shape you asked for.
Input: STL or 3MF · Output: repaired STL — colour and materials are not carried over
